In electronics to “brick” something means to make it non-functional, as this handy Wikipedia entry explains for you. In Massachusetts, they have a state policy of bricking guns before they can be sold in the state, also known as the “approved firearms roster“. An example of that is the Kahr PM9, a wonderful little 9mm carry pistol in its own right, but to get it on the MA Approved list, you have to add a whole bunch of unnecessary parts. Now, while this doesn’t “brick” the gun in the truest sense of the word; I am generally opposed to adding extra parts to guns that are supposed to simple, reliable, defensive firearms. A manual safety on a small hold out pistol is just one more thing to forget to disengage, one more thing that could break at the worst possible moment and produce a “click” instead of a bang.
The same reason why I’m opposed to stuff like that is why I wish that S&W wouldn’t put the internal locks on the J-frame and the flyweight unobtanium revolvers – the guns designed as last ditch defensive weapons. Mechanical things break, and while there are no magic swords, it doesn’t make a whole lot of sense to me to put stuff on your not-magic sword that increases the odds of it going tango uniform at a really bad moment.
Of course, this isn’t really Kahr’s fault; mind you. They have the choice of adding all this ridiculous crap to a perfectly functional firearm in order to meet the arbitrary and nonsensical “safety” standards imposed by the State of Massachusetts. You know, in a perfect world, Massachusetts would be legally liable if a state mandated safety device failed on an MA-compliant version of a firearm and caused injury or death to the legal user/owner.
